I am a faculty member jointly appointed in Computer Science and Cognitive Science at the University of Toronto. My research explores the interplay of language, cognition and computation with a focus on modeling lexical creativity. Natural language relies on a finite vocabulary to express an unbounded set of ideas. I am interested in how humans construct the lexicon to convey emerging meanings through time and in different languages. I take a computational approach to characterize the cognitive foundations of lexical creativity and the functional principles of the lexicon. I also develop methods for understanding diachronic processes such as semantic change and moral change.
